How do you do this problem -14=-20y-7x and 10y+4=2x

Question

anonymous · Answer

depends on what you're trying to solve

mathstudent55 · Answer

You have a system of equations.
There are several methods of solving a system of equations.

One of the methods is called "substitution."
To use substitution, solve one equation for one variable.
Then plug that in the other equation to solve for one variable.

In your case, I'd use substitution, and I'd start by solving the second equation for x.
Can you do that and show what you get?
Then we'll continue.

This is a different type do problem like this one -14=-20y-7x and 10y+4=2x

anonymous · Answer

-14=-20y-7x
+7x            +7x
7x-14=20y
x=?
7x-14=20(0)
7x-14=0
   +14     +14
7x=14
/7    /7
x=2
y=?
7x-14=20y
7(0)-14=20y
-14=20y
/20    /20
-14/20=y
-7/10=y
y=-7/10
